I'm reserving my interest in smart home tech for when it's a clear win in terms of energy efficiency. Very recently I compared my current home lighting costs with a fully smart-equipped setup, and it basically just balanced out. I was surprised, because I calculated a best case scenario where the lights could basically always be off when not in use, compared to my current patterns where honestly I'm pretty lazy and leave all them on almost all day. The industry/general consumer priorities are pretty frustrating.
